Brucite
refers to a mineral form of magnesium hydroxide, Mg (OH)2.
Bumping
refers to violent boiling of a liquid caused when bubbles form at pressure above atmospheric pressure.
Cadmium hydroxide
Cd(OH)2, a white powder, soluble in dilute acids; used to prepare negative electrodes for cadmium-nickel storage batteries.

By-product
a substance obtained during the manufacture of a main chemical product. For example, propanone is now manufactured from propan-l-ol, but is obtained as a by-product in the manufacture of phenol.
Cadmium
a transition metal which is obtained as a by-product during the extraction of zinc. It is used to protect other metals from corrosion, as a neutron absorber in nuclear reactors, and in alkali-type batteries

Cadmium bromate
Cd(BrO3)2, colourless powder, soluble in water, used as analytical reagent.
Cadmium bromide
CdBr2, a compound produced as a yellow crystalline powder, soluble in water and alcohol; used in photography, process engraving, and lithography.

Cadmium carbonate
CdCO3, a white crystalline powder, insoluble in water, soluble in acids and potassium cyanide; used as a starting compound for other cadmium salts.
Cadmium chlorate
CdClO3, white crystals, soluble in water, a highly toxic material
Cadmium chloride
CdCl2, a cadmium halide in the form of colorless crystals, soluble in water, methanol, and ethanol; used in photography, in dyeing and calico printing, and as a solution to precipitate sulfides.
|
Cadmium iodide
CdI2, cadmium halide that forms Iustrous, white, hexagonal scales, consisting of two water-soluble allotropes; used in photography, in process engraving, and formerly as an antiseptic.

Cadmium oxide
CdO, in the cubic form, a brown, amorphous powder, insoluble in water, soluble in acids and ammonia salts; used for cadmium platting baths and in the manufacture of paint pigments.
Cadmium sulphate
CdSO4, a compound that forms colourless, efforescent crystals, soluble in water, used as an antiseptic and astringent, in the treatment of syphilis, gonorrhea, and rheumatism, and as a detector of hydrogen sulphide and fumaric acid.
